Which position in the evacuated-tube order of draw is designated for the green tube?

Explanation:
In the evacuated-tube order of draw, each tube’s additive is chosen to minimize cross-contamination that could affect test results. The green-top tube contains heparin, used for certain plasma chemistry tests. In the standard sequence, it comes after the serum tubes (red and gold/SST) and before the lavender tube (EDTA). That placement keeps heparin from contaminating serum tests and prevents EDTA from affecting other tests. So, the green tube is designated after the serum tubes and before the lavender tube.
